Computer Graphics — Summer 2018

Define: 1) Persistence 2) Resolution 3) Frame buffer.

List the applications of computer graphics and discuss any one.

Explain CRT with neat diagram.

Consider raster systems with the resolutions of 640x480, 1280x1024, and 2560 x 2048. What size frame buffer (in bytes) is needed for each of these systems to store 12 bits/pixel? How much storage is required for each system if 24 bits per pixel are to be stored?
